Gobiatherium (from Gobi Desert, and Ancient Greek θηρίον (thēríon), meaning "beast") was one of the last uintatheriids, from the Mid Eocene of Mongolia.[1]

Description

Unlike its North American cousins, Uintatherium or Eobasileus, Gobiatherium lacked knob-like horns, or even fang-like tusks. Instead, it had enlarged cheekbones and an almost spherical snout. The dental formula of the genus is . The lower incisors were bilobed, and the genus lacks upper canines all together.[2] The lower canines are reduced, and the lower jaw is shallow.[3][4][5][6]

Classification

Because of the noticeable lack of many diagnostic uintathere features, the genus is placed within its own subfamily, Gobiatheriinae, within Uintatheriidae.[2][4][6] Historically, Gobiatherium was grouped within its own family, Gobiatheriidae, alongside Uintatheriidae and Prodinoceratiidae, though this is not supported.[6]
